Abstract

The electrochemical properties of W-modified austenitic stainless steels containing Ta and La were evaluated in a $H_{3}PO_{4}$ type PEMFC environment. Electrochemical test was conducted in 0.05 M $H_{3}PO_{4}$ solution at $80^{\circ}C$ and electrical property was conducted by contact resistance test. XPS was conducted to analyze the chemical elements consisting of passive film. Addition of La and Ta in W-modified austenitic stainless steel shows not only better corrosion resistance but also better electrical property.
